IMPROVEMENT IN DUMPlNG-CARS.

Specification forming part of Letters Patent No. 125,307, dated April 2, 1872.

To all whom it may concern:

Be it known that I, SIDNEY D. KNG, of Middletown,in the county of Orange and Sta-te of New York, have invented a new and valuable Improvement in Dumping-Cars; and I do hereby decla-re that the following is a full, clear,-

and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a side view, partly sectional, of my invention. Fig. 2 is a vertical transverse section of the same.

This invention has relation to a dumpingcar, having two boxes resting on a single platform, one box being movable so that it may be tilted, the other stationary, and adapted to empty from the bottom. The novelty `consists in the arrangement of the car-wheels and axles, the construct-ion of the bottom of the stationary box; and in the construction and novel arrangement of devices applied to the movable car for the purpose of governing its movements, all substantially as hereinafter described.

In the accompanying drawing, Arepresents the platform ofmy improved dumping-car, supported upon two pairs of wheels, B. C C are two boxes of entirely different construction. The -box C is hinged, about midway between the ends, to a movable platform, D, which slides between han ged guides E. F represents rollers secured to blocks e depending from the bottom of the car near its rear end. I4" represents inclined ways at the ends of the guides E, over which the rollers F pass in dumping the car. The end gate Gr has curved sides g, with end projections g1, which, in connection with the flanged plates g2, act as stops to prevent the end gate from falling too far. The

end gate is self-opening, falling by the weight of the contents of the box when the latter isv tilted. Chains H, attached to the ends of the sides g and to one side of the platform, cause the end gate to be closed when the box is moved back to its proper position. To prevent the box from sliding off the platform when moved to the side for tilting, a block, I, is secured to the platform A. Against said block the platform D is brought, and by it held back. Another block, I', is placed at the opposite side of the platform A to prevent the box from moving too far forward. J is a cleat laid across the platform A underneath the box C. This cleat is beveled on one side. A lever, J', is pivoted to the forward end of the platform D, and is constructed with its lower ends beveled to correspond to the bevel of the cleat J. This lever is used as a brake when the box is moving over the inclined planes F by pressing it against the cleat. The handle of said lever is bent in such a manner that when the box is brought to its right position on the platform,

A the lower end of said lever will be thrown in front ofthe cleat, and in such position serve as a lock to prevent the box from moving backward. A stud,., keeps the lever from falling over far enoughl to pass the end of the cleat. The box C is stationary. The bottom thereof is in three parts, cl c2. The parts c1 are inclined downward toward the middle part c2, which is inclined from the end toward the middle of the platform A.

The contents of the box C is discharged at the end of the part c2, where there is arranged either a sliding or a hinged gate, K. The sliding door is operated bya pivoted lever, L, and falls between the rails. The brake-open ating devices L are located between the boxes C C.

The car herein described is designed more particularly for carrying gravel or other Inaterial used inthe construction of railways. The stationary box deposits its contents between the rails at the same time that the dumpingbox deposits its contents to one side thereof. n

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The box C', having chute c2 inclined from the rear end of the car through the platform thereof, as described, and provided with gate K, in combination with a shelving bottom 01 c1, substantially as and for the purpose specified.

2. The centrally-dumping box C andluter- In testimony that I claim the above I have ally-tilting box C upon platform A, as and for hereunto subscribed my name in the presence the purpose speeed. of two Witnesses.

3. The bent level` J havin g its end beveled, SIDNEY D. KING. in combination with the beveled cleat J and Witnesses: movable ear-box C, substantially as and for the' J. M. H. LITTLE 7 purpose spececl. T. N. LITTLE.
